that means that dcerouter didn't work on that time? did you meet troubles?

or it may be posible to got a reload router from UI and that screen to refresh while router was restarting. that screen is refreshe only once per minute, so you could have that red message for a minute but everything was ok.

Looks like another incompletely/wrongly burned CD to me. Try burning your discs at lower speed (16x or 24x, but not higher) if the ISO image that you have is correct. Also notice that there's a new release available (2.0.0.35).
